i am going to be getting a 50g tank tommorow so i need to know what i will need to get the heat up. i know i need a basic basking bulb but what watts should it be? and will this basking bulb be enough to heat up the cage during the day? i don't want to overheat my cage but i also don't want it to not have enough heat in it. ill be using the basking bulb and a reptisun tube for lights, should i also buy a heat pad to get the tempeture up around the tank? all help is appreciated!
